I would ask to sit and do the finances with your husband for a month or two, get an idea of how they are done in case something happens to your husband, illness or death? That way you can see if he has a system that appears to work or is just "winging" it. Take an interest but try not to comment until after you understand it thoroughly? If he is unwilling to share what he is doing at all, to help you, I would address that with him.
